UNEP's Gabriel Labbate on Cookstove Credits, Forest Loss and Article 6.4 Permanence Rules

UNEP climate mitigation lead Gabriel Labbate explains how cookstove carbon credits work and why forest benefits are indirect. Credits are calculated against a baseline of wood or charcoal use, and the real climate risk sits in fNRB, the share of woodfuel harvested faster than it regrows. He argues the fix is better estimates and measured stove use, not permanence buffers built for carbon storage projects. Under Article 6.4, proposed safeguards could deduct more than 30% of credits in countries that rely heavily on biomass, and combined deductions could leave projects in places like DRC and Papua New Guinea with almost no saleable credits. That would cut the carbon revenue that makes cleaner stoves affordable. Labbate says cookstove projects should be treated as avoided emissions activities, with rigor placed on conservative fNRB, usage monitoring, and additionality checks.

Good interview. The key tension is whether Article 6.4 treats cookstove credits like storage projects. Labbate argues permanence buffers fit forests and geological storage, not avoided emissions. The 30% deduction stat for biomass-heavy countries is the one to watch.

The permanence mismatch is real. If you force a 100 year liability on avoided emissions, you should apply it to renewables and fuel switching too. The draft picks on cookstoves partly because they are easier to target. fNRB is the actual measurement problem and that needs better data, not a buffer.

Also worth remembering the social side. If deductions stack, projects in DRC and PNG lose most of their credit revenue. That revenue is what makes stoves affordable. A rule that looks rigorous on paper could just push households back to charcoal.

Question on the 31-42% range from Wu et al. Labbate says it is scenario based, not a statistical uncertainty estimate. If the Supervisory Body uses it as country level percentages anyway, the credits get priced on numbers that do not mean what they appear to mean. That seems like a governance failure in the making.

From a field perspective, the stove adoption and usage data matters more than the permanence debate. A stove that sits unused claims credits based on baseline assumptions that never happened. The interview mentions measured usage, but the draft rules need to make usage monitoring a hard requirement, not an afterthought.
